ranged at intervals'adj acent the band l"6 isa plurality Aof transverse ribs or plates 8,

which aref arranged adjacent certain ofthe openings 7. These ytransverse ribs '8, are riveted or otherwise .secured at 9"to ythe band6 and these rivets 9 securing the band to the rim. Certain trans-a through thev rim Ll, thereby also 6 are provided with hinge rolls 10 between which the hinge rolls 11 of the hinge platesVV 12 (which are secured at 13 to the tractor elements 14) are pivotally mounted by means of the usual hinge pins 15 as shown in Fig. 1. The tractor elements are mounted to move in the openings A5 and 7 of the rim and the band. The openings 5 of the rim are narrower than the openings 7, and it is to be noted that the band is disposed on therim so that certain edge portions of the openings 5 will protrude beyond certain corresponding edge portions of the openings 7 at positions opposite the hinge-connections of the tractor wheel elements so that when the tractor elements are collapsed, their outer edge portions will partially countersink within the openings 7 at points opposite the hinge connections. Secured as at 16 to the trartor elements are braces 17. These braces are angular in cross section as shown, and thev flanges 18 at certain of 4their ends terminate in ears 19, adjacent which are opposite ears 20. These ears 19 and 20 receive pivot pins 21.

Referring to Fig. 2vit will be noted that a portion of a tractor frame 21a is illustrated, and also a part of the drive shaft 22. `The tractor wheel is carried by the drive shaft 22 and comprises the concentrically arranged opposed plates 23 and 24, which are bolted together as at 25. Additional bolts 26 pass through the concentric opposing plates near their marginal edges,and pivotally mounted on said bolts 26 are links 27,'which in turn are pivotally mounted upon the pivot pins 21 of the tractor element. These opposing concentric plates are movable relatively to the rim of the wheel and when moved, they constitute means to movethe tractor elements to extended positions, or to collapsed positions as shown in Figs. 1 and 3 of the drawings.v Bolted or riveted or otherwise secured to the plate 23 is a hub member 29, which is pinned to the drive shaft 22 by means of the dowel pin 30.

The tractor wheel is provided with an'ad! ditional wheel plate 31 provided with radial spokes 32 having their outer ends terminating in right angular lugs 33, which are bolted at 34 to the rim and the band 6. Carried lby the drive shaft 22 and fixed thereto as at 35 is the hub of the drive gear 36. Ashaft 37 adapted to be drivenV by any suitable power is provided, and rotatable ktherewith is a gear 38 which meshes with the lgear 36, so as to impart movement to the drive shaft 22. Mounted in guide openings 39 of the wheel plate 31 are pins 40. These pins 40 are lsecured at 41 to'avdisk plate .42. The 42 has an opening which fits the hub ofthe drive gear 36. The pins 40 pass` through arcuate slots 43 oi". the drive gear 36, so that it is possible for the drive In this gear to move partially without being interi rupted by the pins 40. The plate 24 is in the form. of a ring as shown, therefore its opening44 is large enough to permit of the use of theyoke 45. This yoke 45 is adjacent the plate 23, and is secured in any suitable manner as at 46 tothe outer ends of the pins 40, so that the yoke is movable with the pins, and since the pins Vare. movable with Ythe wheel so listhe yoke 45. rlhe pins 40 pass through arcuate slots 47 of the plate 23 of the Wheel. Theyoke at diametrically opposite portions is provided with projections, the ends of which terminate in lugs 48, which normally engage through one s'et or the other of the openings 49 and 50 of the plate 23, thereby holdingthe plate'in different adjusted'positions, according to the position of the tractorelements.' The yoke 45 is provided with afboss 5,1 on one face, and also a laterally projecting pin Y52. pin passes transversely through the plate 53. which is bolted or otherwise securedy at 54 to the wheel platel. A coil spring 55 is vcoiled about the boss 51, and is interposed between the yoke andthe plate'53, and facts to hold the lugs 48 in either set of] the openings 49 and 50, to vhold collapsed or extended? One end of the' coil spring 55'is formed." into an eye which 'engages the pin 52, thereby retaining' the coil so that bothvv cams can move together when one is operated. An arm 59 iscarried by one ofthe cams disposed the tractor elements Y This j and are provided `with laterally extending arms`57, which are .connected by the link 58,

and hasY va link 60 connected thereto, `which in turn is connected to the lever 62mounted upon the tractor frame so that bylmoving thelever in one direction, causing Vthe cams to apply pressure upon the plate 42, the pins 40 will be moved outwardlyycausing the lugs 48 to disengage certain ofthe openings49 and 50, and then bypower being transmitted to the gear 36, the plates. 23

and 24v will move relativelyto the rim, and through the vconnection with the tractor elements saidv elements will be moved radially in positions, so that the wheelmay'take hold 1n sandy,"mud'dy or otherwise bad lroad beds,

in order ,tof cause the tractor to move and travel vvery rapidly andwithout slipping.

When the plates423 and'24-are moved in the opposite direction the tractorelements may be collapsed to the position shown inF ig. 3.

case the'lugs of the'yoke will disengage from the openings .50 and by movement of thegear 36 inra reverseV direction, the tractor elements may be collapsed, which l will vbe assisted considerably bythe weight of the tractor.

The invention having been set orth,What is claimed as neWrand useful is:

l. In a tractor Wheel, the combination with a rim provided With spaced openings, of blade tractor elements pivotally mounted in said openings, carried by the Wheel and being connected to said tractor elements for movingl them to radial or collapsed positions, and means for locking said tractor elements, saidV means comprising a yoke guidable concentric with the Wheel and having means to engage certain of said plates, to hold the tractor elements either radially Vextended or collapsed, spring means for said yoke, and manually operated cam means coperatively connected with said yoke for moving the yoke.V

2. In a tractor Wheel, the combination With a rim having tractor elements movable to radial tractor positions or to collapsed positions, of means movable With the Wheel when in action, but movable relatively to the rim and having lconnections With the means concentric With and dial tractor positions, and alocking device for said means to hold the tractor elements in extended or collapsed positions.

3. In a tractorv Wheel, the combination i with a rim provided With a plurality o tractor elements` movable to radial or collapsed positions relativeto the rim, means movable with thewheel and being movable relatively to the rimand 'having connections With said tractor elements Jfor changing their positions, a locking device or'said means, said locking device comprising a spring tensioned yoke carried by said means and being movable laterally. relative thereto and means carried by the Wheel and connected to the yoke for imparting lateral movement to the yokev to permit the tractor element actuating member to be moved.

In testimony whereof I hereuntoaiiix my signature.
